"Keep the course and raise the periscope!" Cal. Heinck took off his white battle cap and buckled it back on his head.

"Okay captain, raise the periscope." Lieutenant Zeko, the deputy captain, flipped the switch on the control board, and searched for the periscope to quickly ascend from the shaft in the middle of the command module to the sizzle of the motors.

"Azimuth zero three-zero, high-speed propeller, captain." The sonar operator poked his head out of the doorway of the sonar room and reported.

"Azimuth zero-three-zero..."Heinck unfolded the folding handles on either side of the periscope, his eyes on the eyepiece with rubber pads.

"Battleship, [King Kong] class, five thousand seven miles away." Heinck said the co-captain stood on the other side of the periscope and took the readings on the dial.

"Another [King Kong]-class battleship, four thousand nine miles away. Record the course... Two-one-zero. ”

"Heading 210, Captain." The co-captain reports the reading.

"Speed twenty knots, five thousand six hundred, two cruisers, three destroyers .... No, it's four, they didn't find us. Heinke folded the armrest of the periscope.

"Put away the periscopes, now let's see...", the captain walked briskly to the chart table, picked up the compass and measuring stick and began to calculate the course.

"They didn't perform an anti-submarine maneuver, they were just a bunch of targets, and we could turn to zero and six zero and cut to their inner line." Heynck said to the co-captain.

"Okay captain, Norman, fifteen degrees on the right side, full speed with both cars, heading for zero sixty." The deputy captain ordered.

"Obey, fifteen degrees on the right side, two cars at full speed." The Chief Navigation Officer snapped the helmsman's shoulders and shouted back.

U1001 has been at sea for 14 days, and she was originally going to return to the temporary anchorage on Kunshan Island today to rest.

The German Navy's U-C submarine (where C stands for Greek letter 100) has entered the final stage of seaworthiness tests in tropical waters, and the data proves that the U1001 is fully capable of adapting to this sea environment, as long as there are no problems with the cold storage on the submarine, the crew does not care about the hot climate here.

An hour ago, Heinke received an order from the fleet command to turn around, when U1001 was still diving fifteen meters underwater, which is the characteristic of long-wave radio stations, which can penetrate seawater and communicate one-way with submarines at a depth of eighteen to twenty meters.

The identity of the U1001 is more sensitive, this is the latest German submarine model, and it has never appeared in public, so it has always maintained a sense of mystery in Indochina, never surfacing during the daytime.

In fact, for the U1001, there is not much difference between the water and the water, and the underwater speed of this boat is a little higher than that on the water.

The order of the fleet command was for her to immediately rush to the coordinate sea area, monitor the actions of the Japanese fleet and, if possible, test the anti-submarine capabilities of the Japanese. Because the U1001 was the closest German submarine to the conflict zone, the command really didn't want to use this valuable prototype if it didn't really find manpower.

In order to reach the target area within the specified time, Captain Heinck led his team to tap all the potential of this submarine, and ran at an underwater speed of 19.2 knots, which is more than most conventional diesel-electric submarines in later generations.

By the time they arrived at the coordinate area, the Japanese and French fleets had already encountered each other, and the two sides were in high spirits engaged in a mock naval battle.

"The Imperial Japanese Navy did not have the most basic anti-subconscious mind, they didn't even know about our existence, and now I'm going to prove it." Heinck raised his wrist to look at the time on his watch, and then began to climb up the staircase up the conning tower.

Opening the protective cover, the captain sat down in front of the attack periscope.

"It's like ducks in a playground pool, look at these big guys." Heinke leaned in front of the periscope eyepiece and turned the crank, and the Japanese battleship in the telescope seemed to be close at hand.

"The speed is still twenty knots, the course is two-two-one, if we fire a torpedo now, what do you say?" Heinck asked the co-captain in the command cabin aloud.

"It will start a naval battle, and then General Dönitz will screw your head off with his own hands, Karl, this joke is not funny at all." Zeko teased as he typed into the ballistic computer the target parameters measured by the attack periscope.

"Torpedo one, two, then three, four. And then..."boom"... The battleship is finished. The boatswain gestured to the navigator for the ship to sink, and the navigator laughed and punched the non-commissioned officer in the shoulder.

At this moment, a dull roar came from outside the boat, and at this time the submarine was moving at a quiet speed of six knots, and the explosion under the water was particularly clear.

"What's going on? Feed! Cal! The co-captain shouted as he leaned up the ladder towards the control tower hatch.

"That cruiser exploded all of a sudden, and I don't know what happened? Hey, don't look at me like that, I didn't do anything! Heinke replied, holding the hatch.

"You should really come up and take a look at this, the whole middle of the ship has been blown up into the sky, it looks like an ammunition depot or something... Oh, the fire is burning..."

"Direction one two zero, high-speed propeller." A sonar warning sounded in the cabin.

"Destroyer, a Japanese destroyer, she seems to see us. Dive! Zeko, dive urgently! Put away the periscope!" Heinck closed the protective outer plate of the attack periscope, then climbed the elevator into the command module, quickly locking the pressure-resistant hatch that led to the enclosure.

Rear Admiral Corinne witnessed the explosion of the heavy cruiser [Furutaka] on the bridge of the "Dunkirk", and the momentum was still very amazing when viewed from 12,000 kilometers away.

No one present knew what was happening on the Japanese side, and even most of the captains thought it was a Japanese battleship firing at them. All kinds of inquiries rang out on the radio, and the slower ones were still asking what had just happened, and the quick ones had already asked the flagship for permission to fire.

On the other hand, the Japanese fleet is now in chaos. Everyone wanted to know what had happened to the Eagle, but no matter how much the flagship asked, the Heavy Patrol never gave any response.

After all, these are professional soldiers with professional skills, and no one thinks that the explosion has anything to do with the French fleet in front of them, because if the French fire, so many pairs of eyes up and down here, staring at the high-powered rangefinder, will be discovered at the first time.

Obviously, this is the [Ancient Eagle] itself had an accident, as for what the exact reason is, we can only wait for the [Ancient Eagle] to explain itself.

What Takasu is most worried about now is whether the explosion of the [Furutaka] will cause misunderstanding among the French, because the French fleet has already turned the rudder and distanced itself, obviously regrouping and preparing for artillery combat.

"[Ancient Eagle] has replied!" A staff officer reported aloud with a telescope.

"The commander of the warband, the captain of the ship was seriously injured... The deputy chief was killed... The hull is cracked .... Request for help! The staff officer read word by word as he translated the light signal on the other side.

"Order the Twentieth Destroyer and [Gagu] to go to the rescue immediately, and the fleet will stop advancing and go all out to rescue [Guying]."

Takasu also knew that he would not be able to understand the cause of the explosion for a while, and now the key was to save this precious warship of His Majesty the Emperor, if he saw the loss of [Kotaka] here, the career of the Fifth Fleet from him, the commander-in-chief of the fleet, to the combat staff officer, would also end here.

The most troublesome thing for Takasu is that this incident happened in front of the French fleet, and the face of the Imperial Japanese Navy was wiped out at this moment, and if it was placed in the Meiji period, it was enough to make the person in charge of a major crime.

"Azimuth 240, 1,500 meters, found periscope." The watchman's shouts brought Lieutenant General Takasu's thoughts back to reality.

"Oh Mocasi to break (right full rudder)" The captain immediately reflexively gave the order to turn the rudder.

"Bridge more sacks! (Wait a minute) could be a French submarine. Takasu's mind was in turmoil at this time, and he really didn't want to make any more trouble.

"[Yutachi] of the second expulsion team rushed up." A staff officer reported aloud.

"Okay, order her to drive away the submarine, but not to attack, that's the commander's order." Takasu turned around and walked towards the bridge staircase, ready to go to the deck to personally direct the rescue operation against Furutaka.

"Hah! Signal Yutachi now! The signal commanded loudly.

"Flagship command, drive ... Submarine.... Attack..."The signal soldier on the [Yutachi] struggled to read the banner issued by [King Kong].

"Roar, the [Xili] is moving forward at full speed POI." Captain Terutomo Arimoto stood on the open bridge and waved his arm forward.
